Summary: Predicted to enable ferrous iron transmembrane transporter activity; identical protein binding activity; and peptide hormone binding activity. Predicted to be involved in intracellular iron ion homeostasis and iron ion export across plasma membrane. Predicted to act upstream of or within several processes, including multicellular organismal-level iron ion homeostasis; positive regulation of transcription by RNA polymerase II; and spleen trabecula formation. Predicted to be located in several cellular components, including cytosol; nucleoplasm; and synaptic vesicle. Predicted to be active in basolateral plasma membrane. Human ortholog(s) of this gene implicated in hemochromatosis type 4. Orthologous to human SLC40A1 (solute carrier family 40 member 1). [provided by Alliance of Genome Resources, Dec 2024]

Ferroportin-mediated ferroptosis involved in new-onset atrial fibrillation with LPS-induced endotoxemia.
Title: Ferroportin-mediated ferroptosis involved in new-onset atrial fibrillation with LPS-induced endotoxemia.
ata thereby indicate that heat stroke can decrease learning ability and memory in rats. The mechanism may be related to changes of iron levels, as well as Fpn1 and hepcidin expression, in the hippocampus.
Title: Dysfunction of Iron Metabolism and Iron-Regulatory Proteins in the Rat Hippocampus After Heat Stroke.
These data point towards a transcriptional induction of Fpn in response to changes in cellular iron levels.
Title: Hepcidin Mediates Transcriptional Changes in Ferroportin mRNA in Differentiated Neuronal-Like PC12 Cells Subjected to Iron Challenge.
Data suggest that expression of ferroportin in intestinal mucosa can be regulated by dietary factors; here, partially hydrolyzed guar gum up-regulates expression of ferroportin in cecum mucosa in growing rats being treated for iron deficiency anemia with this probiotic; intestinal absorption of dietary iron appears to be up-regulated, as well.
Title: Partially Hydrolyzed Guar Gum Increases Ferroportin Expression in the Colon of Anemic Growing Rats.
The significantly increased FPN1 level in small intestine facilitates digestive iron absorption, which maintains the serum iron concentration at a near-normal level to meet the increase of iron requirements
Title: Effects of Pregnancy and Lactation on Iron Metabolism in Rats.
DMT1 and FPN1 are positively influenced by ferrous iron status in brain after intracerebral hemorrhage. DMT1 and FPN1 attenuate iron overload after ICH via increasing transmembrane iron export.
Title: Changes of ferrous iron and its transporters after intracerebral hemorrhage in rats.
the effects of hepcidin expression and hepcidin peptide on brain iron contents, iron transport across the brain-blood barrier, iron uptake and release, and also the expression of TfR1, DMT1, and Fpn, were investigated.
Title: Hepcidin Suppresses Brain Iron Accumulation by Downregulating Iron Transport Proteins in Iron-Overloaded Rats.
Hepcidin or enterocyte iron levels may be involved in the regulation of the age-dependent expression in the duodenum.
Title: Age-dependent expression of duodenal cytochrome b, divalent metal transporter 1, ferroportin 1, and hephaestin in the duodenum of rats.
In ischemic rats, Fpn1 expression in the cerebral cortex and hippocampus was decreased.
Title: Quantitative analysis of iron concentration and expression of ferroportin 1 in the cortex and hippocampus of rats induced by cerebral ischemia.
Data suggest that expression of ferroportin (Slc40a1) in intestinal mucosa can be regulated by dietary factors; here, expression of ferroportin in mucosa of duodenum is down-regulated by prebiotic supplement, oligofructose, in iron-deficiency anemia.
Title: Effects of prebiotic supplementation on the expression of proteins regulating iron absorption in anaemic growing rats.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
